Daniel Dai commented on PIG-1910:
---------------------------------
PIG-1910-1.patch fix the test case in description.
For the other test case in comments, I get:
Invalid field projection. Projected field [b] does not exist in schema:.
Which seems fine. We have no way to translate g into logical plan since we
don't know how to translate b into right position.
> incorrect schema shown when project-star is used with other projections
